对游憩场地选择的表态偏好模型和显性偏好模型进行了检验和比较。这两个模型都基于随机效用理论，数据都是从相同的人那里获得的。所述偏好模型是基于被调查者从假设选择集中所做的选择。所述偏好模型中的属性基于所显示的偏好选择集中的属性的实际水平的范围，并使用部分析因统计设计呈现给受访者。结果表明，虽然独立估计的模型似乎反映了不同的潜在偏好，但模型参数的联合估计，包括对相对规模参数的估计，提供了基本偏好实际上是相似的证据。此外，将揭示的偏好信息和陈述的偏好信息结合在一起，在估计中产生了其他好处。(C)1994年学术出版社。
A stated preference model and a revealed preference model for recreational site choice are examined and compared. Both models are based on random utility theory and the data are obtained from the same individuals. The stated preference model is based on the respondent's choice from hypothetical choice sets. Attributes in the stated preference model are based on the ranges of the actual levels of attributes in the revealed preference choice set and are presented to respondents using a fractional factorial statistical design. The results show that while independently estimated models appear to reflect different underlying preferences, joint estimation of the model parameters, including estimation of the relative scale parameter, provides evidence that the underlying preferences are in fact similar. Furthermore, combining the revealed and stated preference information yields other benefits in estimation. (C) 1994 Academic Press, Inc.
